Sequenceff
N-Terminal ModificationFree
C-Terminal ModificationFree
Non-terminal ModicationNone
Length2
Peptide/Conjugate/MixturePeptide
Conjugate PartnerNone
TechniqueTransmission Electron Microscopy (TEM)
SolventAqueous dispersion
MethodNH2-D-Phe-D-Phe-COOH dipeptide solublized at very high concentrations ( >=100 mg/ml) by dissolving the lyophilized peptide in 1,1,1,3,3,3 hexafluoro-2-propanol. The peptide appeared to be highly soluble in the organic solvent, a rapid assembly into ordered semicrystalline structures was observed visually within seconds after dilution into the aqueous solution at a final µM concentration range.
Concentration>=100 mg/ml stock soln
